A relationship is composed of many things:  friendship, sexual attraction, intellectual compatibility, and, of course, love.  Love is the glue that keeps a relationship strong and solid, infidelity breaks it.  But how do you know if you are truly in love? 

The general idea about why people cheat while in a serious committed relationship, is that there is a problem with either the cheater or the relationship.

 Often, we assume that cheating is a pathology, some unresolved dysfunction, or often a form of emotional immaturity, that pushes them into infidelity.

Helen fisher said in a ted talk (2006): “we evolved three basic drives: the sex drive, romantic love and attachment to a long-term partner. These circuits are deeply embedded in the human brain. They’re going to survive as long as our species survives on what Shakespeare called “this mortal coil.”

Why do people cheat on each other?
